Would it be possible to get tar to copy (or ignore) file attributes, and to copy ACL's if they exist ( maybe via an option)?

Some attr's I really like to keep on files, and end up having to use something a host of different utils (depending on fs and os), but
common examples are the '+d" 'don't dump' attribute ...

This kind of file attribute (nodump, immutable, append-only, etc) isn't
backed up by tar yet, not even the ones that already back up extended
attributes (e.g. recent RHEL/FC tar with xattr patches).

Actually, star has supported this for a long time, and bsdtar adopted the star approach (the SCHILY.fflags attribute) a couple of years ago. It would be nice if GNU tar also supported the same mechanism. I don't know whether Solaris, HP, or AIX tar support it.

ACL's -- those would be most useful for me under Cygin-Windows....

ACLs are backed up by the patched RHEL/FC tar programs.

Are those supported on Cygwin/Windows? I thought the RHEL/FC patches only supported Linux.
